It's OK to step up the graphics requirements for a game as long as you still support the lesser boxes with a fallback. I do think that the GPG games are good in that respect in having both automatic and manual settings for how much you want to stress your video card.
That's one of the reasons I mentioned Oblivion as an example of the way developers should be thinking... it supports my video card even though it is about 5 years old (but that's not the computer I play on now), and the game has an extremely detailed ini for tweaking tons of settings affecting performance (level of detail, shaders, bloom lighting effects, water reflections, show grass, show distant landscape...). Admittedly I had to turn off all the eye-candy in order to play on the old machine, but the game did run fine (for as long as I tried playing on that machine). Plus, I know that there are low-texture packs (mods) available if I need them.
As for the swirling colours, you know I agree with minimizing them. Oblivion does have some, but they are not "always on"... they're only displayed when being actively cast (or if you're receiving fire damage over time, it looks like you're on fire...). This can be distracting during magic intensive battles (especially with multiple combatants using enchanted weapons) but I find it to be appropriately done (as realistic as something like that can be).
